With Europe melting away under unprecedented heat, one of the best ways to lower tempretures and protect soil and foliage from dry out is by planting trees and other plants and restoring forests and meadows. There are a few ways to do this, community gardening groups are becoming more popular, there's also a service called Bee Bombs that sells seeds to turn private gardens into wild flower patches for bees. And the ecosia search engine uses ad revenue to fund tree planting 150million+ so far.
